STOP-MOTION FOR SPINNING AND TWISTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 279,870, dated dune 19,1883.

Application filed September 26, 1882. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM G; Hmvnnn, a citizen of the United States,residing at- Springfield, in the county of Hampden and State ofMassachusetts, have invented new and useful Improvements in Stop -lVIotions for Spi nning and Twisting Machines, of which' the following is aspecification.

This invention relates to stop-motion devices for spinning and twistingmachines, and has pende'ntly of the others, the object being to insurethe stoppage of a spindle if the material which is being twisted thereonbreaks either above dr belovi the feed-rolls of the machine.

In the drawings forming part of this specification, Figure I is a sideelevation of stopmotion devices, partly in section, embodying myimprovements. Figs. II to V, inclusive, are detail views of the same.Fig. VI is a side elevation, partly in section, showing the operativeparts of the twisting mechanism of a spinning-machine having myimprovements applied thereto. I

In the drawings, A is the end of the front board of the twisting-frame.

B is the drop-wire frame, secured in an inclined position upon the frontside of said board. a

0 indicates drop wires adapted to have strands of yarn or other fibrousmaterial pass through proper eyes formed 011 their ends, and pivoted atthe lower end of frame B, and provided with enlarged lower ends, a",standing nearly in a horizontal position when yarns are passing throughsaid eyes. Said parts 0 are adapted to overbalance the weight of the11pwardly-projecting parts 0 of the drop-wires.

D is a yoke-frame secured to the rear side of board A, the form of whichis shown in Figs. I, 11, IV, V, and VI. Eis a latch-rest hung on ashaft, o between the sides of frame D, and consists of the verticalleaf0, provided with two bosses, 0 0 on its lower edge, through which saidshaft otpasses, anda roller, z, hung on said shaft between said bosses,and adapted to rotate thereon. A drop-wire yoke, e, of rectangular form,is secured to the bosses 0 on said latch-rest, and reaches forward underthe ends 0 of the drop-wire c. A frame, 6 is likewise secured to saidbosses and projects rearwardly therefrom. An adjusting-screw, o, isplaced in theleaf 0 of the latch-rest, for the purpose of adjusting thedegree of the engagement of the latch with said rest, as hereinafterfully set forth. A vibratory eye-wire, a, is pivoted to the lower end ofthe frame D, and connected therewith, near the latter, is a weight, (Z.Said eye-wire is adapted to reach down just above the end of the spindleof the machine, and have the yarn f pass through its eye, holdingitslower end forward, as shown in Fig. I. A rearwardly-proiecting arm, a issecured to the same axis with the wire a and extends under said frame awhich is secured to the latch-rest E.

I6 16 are the drawing-rolls, 17 is a sect-ion of the ring-rail, 1 8 isthe bobbin, and 19 is asection of the frame of the machine.

The kind of spinning-frame herein illustrated and to which myimprovements are applicable is that wherein each spindle is arranged tobe started and stopped independent- :on which is secured a band-guide,11.

Fig. VI illustrates the co-opcrative parts of such a frame as is abovedescribed, together with the stop-motion devices herein described,showing the spinning and stop-motion devices in their operativerelations. Each spindle and its stop-motion mechanism is but a'duplicateof the others on the frame, amlthereibrc one spindle and itsaccompanying parts clearly show the construction thereof. The usualdriving-band, 12, passes around the drum 13, through said guide, andaround the spindle whirl 14 of the spindle 15. Said spindle is providedwith a tight and loose whirl of any well-known construction, to providefor shipthe lower end of latch i swings back and rests stop and startthe upon the roller 2 on the latch-rest E, and

against the side of the leaf 0 thereon, thereby holding rod h in anupward position. The weight of the rear arm, 0 overbalances that of theyoke e, and therefore, when nothing obstructs the free oscillatorymovement of the rest E, and said arm or frame 6 and yoke 6,

the said parts will swing to the position shown in full lines, Fig. I,which, brings the latch-rest E to a proper position to receive thereonthe lower end of latch 1', whereby rod h is held up.

The aforesaid latch-rest E is shown in front elevation in Fig. V in theyoke-frame D, hung in the latter by the shaft '0 and centrally in saidlatch-rest is located the roller .2, on which the end of latch i restswhen the shipper-rod h is lifted up to start the spindle and hold theband onto the spindle-whirl. The lower end of latch 41 may 'be allowedto take a position on said roller directly over the shaft c", on whichsaid roller is hung, or a little to one side of said shaft, by adjustingthe screw othrough the leaf 0, so that when said latch swings over saidroller it will hit the end of said screw, and as the latter stands in aline across shaft o and roller 'z, the position of the end of the latchon the latter will be governed by the projection more or less of the endof said screw over said roller. The oscillation of the latchrest E todrop the shipper-rod h and stop the spindle carries leaf 0 and screw 12against the back side of latch z, forcing its .end off from roller 2,and the end of said latchis more easily pushed forward and off from saidroller if it does not stand too directly over said shaft 2 This providesfor operating yoke c and said latch-rest by very lightly weighted ends 0of the drop-wires e. The oscillating latch-rest E may be made withoutthe roller .2, which c0nstitutes a rolling bearing for the end of latch'13, by making that part thereof in which said roller is hung solid butthe resistance of said latch against displacement from such a rest wouldnecessitate very heavy parts 0 on the drop-wires, and consequently causesuch a back draw on the yarn f as would render it difficult to sustainsaid wires in a forward position, when running very fine silk or othermaterial, without running the risk of often breaking the strand. Thelocation of said adjusting-screw o in the leaf 0 contemplates theswinging of the rest E to the position shown in Fig. I, when it is toreceive the end of latch i,- but said screw may be put through a part offrame D and made to operate against the rear side of leaf 0, swingingits upper edge toward latch 13, and the result relative to the bearingof the end of the latter over the axis of roller 2 would be the same asis effected by said screw when operating through said leaf. The leaf 0,standing up behind latch 1', serves, when yoke e is forced down, to pushthe end of latch 2 off from roller 2, letting rod-h drop down, with theresultabove stated. When the yarn f is passing regularly down to thespindle unbroken and under proper tension, the wire a and arm a areretained in the positions shown in full lines in Fig. I; but ifsaid yarnbreaks or slacks up, said parts swing to the positions shown in dottedlines in said figme.

It is desirable, in machines of the class to which the above-describeddevices are applied,

that the shipper-levers h should not drop down and unship the bands whenthe yarn slacks up because of the stopping of the whole spinningframe,as would be the case were no provision made, independent of thestop-motion proper, for preventing the latch-rest E from being operatedby the slacking of the yarns under such circumstances For the purpose ofpreventing theshipperlever h from dropping when the machine is stopped,as just described, a latch-rest holder, y, is provided, which is securedto an arm, 76, and the latter is secured to a shaft, 02, which issupported on the rear side of the, board A. When the operator is aboutto stop the machine, shaft n is turned to bring the holder y downontoframe e", as shown in dotted lines in Fig. I, whereby the latch-rest Eis held stationary, and the ends 0 of the drop-wires a may rest on yoke6 when the yarns slack up without causing the rod h to drop down. Holder9 operates in like manner to prevent said latch-rest from being operatedby the movement of arm a" up against frame 0* from the same cause asabove stated.

The holder i may consist of a single piece secured to an arm, 7r, foreach spindle; or it may be a suitable strip or rod running in the rearof board A, from end to end of the ma chine, which can be swung onto andoff from all of the frames 6 simultaneously.

The operation of the combined parts of the shipper-rod and latch and thedrop-wires, latclrrest, and eyewire a. is as follows: The yarn f, havingbeen'passed through the dropwire 0, and thence around the usualfeed-rolls, and then through the eye-wire a, is attached to thespindle-bobbin in the usual manner. Rod h is then lifted up to start thespindle, the tension on the yarn draws the wires 0 and a to thepositions seen in full lines in Fig. I,

and the latch-rest E, yoke e, and frame 0 all assume the positions thereshown; and upon raising rod h the lower end of latch '12 is brought torest upon the roller 2 thereon, whereby rod h is held in the upwardposition there shown.

The frame B is adapted to support a series of wires, 0, to provide forgoverning and supporting several threads which are to be twistedtogether below. When any one of the said threads breaks, or from anycause becomes so slacked that it does not retain the wire cin theposition shown in full lines in Fig. I, against the counterbalanceaction of the lower end, 0 of said wire, the latter swings back and itssaid end falls on the yoke 0, bearing it down, as shown in dotted lines,and turning the latch rest E on its shaft o, causing the leaf 0 tostrike the back side of latch 17, whereby the lower end of the latter ispushed forward, and the roll 2 rotates, carrying said end entirely offrom said rest, and rod h drops, and the band is thereby shipped and thespindle is stopped. When said rod drops, the lower end of latch i hangsdown in front of rest E, slightly out of a perpendicular line, so thatwhen said rod is again lifted up the lower end of the latch will swingback again onto the rest E, as before. The slacking up or breaking ofthe yarn at or near its engagement with the lower end of wire a allowsthe latter to swing to the position indicated in dotted lines in Fig. I,thereby producing the same effect upon the rest E, by driving frame 0*upward, as was produced by the back fall of wire a, as above described,

the two positions of which are shown. in full and in dotted lines inFig. I.

The construction of the latch-rest E with the leaf 0 and roller 2thereon, the latter operating on a small shaft, makes a device for thispurpose which, while ample for the support of the weight of theshipper-rod, can be operated to drop the latter by a very slight weighton the yoke 6. Therefore by making the Wires 0 with short unweightedends in place of those lettered c and hanging them in frame B, so thatthey would of themselves swing backward.

when permitted to do so, the weight thereof would be sufficient to tipyoke e and disengage the latch from the rest E.

What I claim as my invention is 1. In combination, the shipper-rod h,the latch .2, one or more drop-wires, c, the pivoted latch-rest E,provided with the yoke e, and with the leaf 0 and the roll 2,substantially as set forth.

provided with the frame e, of the latch-rest holder y, pivoted over saidframe, substantially as set forth.

5. In combination, the shipper-rod 71, the latch 2', hung on said rod,the oscillating latch- 45 rest E, having therein a rolling bearing forthe end of said latch, substantially as described, and provided with theupwardly-pro ecting leaf 0, having therethrough the screw 2;, whosepoint extends over said rolling bearing, sub- 50 stantially as setforth.
